The 400W ATX linear power supply default input is 220V AC (support max 260V AC). Please push red switch down to 110V position if you are in 100V-120V AC area.

Plug the AC power cord (AC power cord is not included). Switch the power button ON. The LCD screen will show the current output voltage for the adjustable 9V output. The adjustable range is from 7V-19V.

Adjust the knob clockwise to increase the voltage and anti-clockwise to decrease the output voltage.

Please connect the ATX cable with the narrow latch clip to the 400W ATX linear power supply ATX output. The head with the wider latch clip connects to the input of the HDPLEX ATX modular bridge board.

Press the latch clip when plug. Once the ATX cables are fully plugged into the 400W ATX linear power supply ATX output, they will be difficult to be disconnected. This is to guarantee robust connection. If you need to disconnect the cables, press the latch clip and move the cable head up and down a little bit to disconnect.

Install four special 3mm height copper post to the HDPLEX H5 back plate and install the HDPLEX ATX modular bridge input board to four copper posts. The side with the smaller board is installed inside H5 back plate.

Plug the internal ATX cable bundle into the ATX Modular bridge outputs first before mounting the H5 black plate to the HDPLEX H5 chassis.
